I need some help! My 1991 taurus with the 3.0 keeps dying on me. It runs fine when its cold, but as soon as it warms up it wont take any throttle pressure....push the gas and it dies. It has a brand new throttle position sensor,new fuel filter, and a new mass air flow meter. I had a conical filter on and then I put the stock airbox on and it still does dies. Any suggestions would be a big help. Could it be the fuel pump?
